Hi I am trying to implement a pass through SOAP proxy via @RestController in spring. For this purpose I have mapped a rest controller in following way:
@RestController
class MyProxy {
@PostMapping(value = "/**")
public ResponseEntity<String> proxyPost(@RequestBody(required = false) String body, HttpServletRequest request) {}
}
The regular SOAP requests are going OK. The problem comes when a MTOM type of SOAP request is send via the proxy. Then spring failes with unrecognized content type. Here is the exception:
Caused by: org.springframework.web.multipart.MultipartException: Failed to parse multipart servlet request; nested exception is javax.servlet.ServletException: Unsupported Content-Type [multipart/related; type="application/xop+xml"; boundary="uuid:dacf4733-80b4-41bc-b2e1-db69b6beadf6"; start="<[email protected]>"; start-info="text/xml"], expected [multipart/form-data]

When receiving a multipart/* request Spring delegates this to the configured Multipart handler. This is enabled by default and for this case should be disabled.
spring.servlet.multipart.enabled=false
Adding the above to your properties should disable it and prevent the parsing, so you can handle it in your controller.
